Methylation Changes of Lysine 9 of Histone H3 during Preimplantation Mouse Development
1 Dec 2005
Abstract excerpt
Immediately after fertilization, a chromatin remodeling process in the oocyte cytoplasm extracts protamine molecules from the sperm-derived DNA and loads histones onto it. We examined how the histone H3-lysine 9 methylation system is established on the remodeled sperm chromatin in mice. We found that the paternal pronucleus was not stained for dimethylated H3-K9 (H3-m2K9) during pronucleus development, while the...
